Abstract
:1. Introduction
- (i) We built a test system for EVSE in accordance with relevant standards, including ISO/IEC 15118, IEC 61851, IEC 61850-90-8 and HPGP.
- (ii) We built the first conformance test system for ISO/IEC 15118 that can test the communication between EVSE and the operator.
- (iii) We developed a reference EV charger that implements IEC-61850-90-8.
